Current approaches in laboratory testing for SARS-CoV-2.

ABSTRACT: The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which began in Wuhan, Hubei Province, China, has rapidly spread to produce a global pandemic. It is now clear that person-to-person transmission of SARS-CoV-2 has been occurring and that the virus has been dramatically growing in recent months. Early, rapid and accurate diagnosis is of great significance for curtailing the spread of SARS-CoV-2. There are currently several diagnostic techniques (e.g. viral culture and nucleic acid amplification test) being used to detect the virus. However, the sensitivity and specificity of these methods are quite different, with the sample source and detection limit varying greatly. This study reviewed all types and characteristics of the currently available laboratory diagnostic assays for detecting SARS-CoV-2 infection and summarized the selection strategies of testing and sampling sites at different disease stages to improve the diagnostic accuracy of Coronavirus Disease 2019 (COVID-19).
